bioinformatics - Databases for gene regulatory network graphs?

I highly recommend you to visit Pathguide to get a sense of how vast is the catalog of Pathway Databases. Looking into the category Pathway Diagrams or in Transcription Factors / Gene Regulatory Networks should help in your task.

I would start by looking at these DataBases:

• GeneMania


• BioCarta


• WikiPathways


• Reactome

If you are working with a species other than human, perhaps you'll find a more suitable database in PathGuide.

Good luck!
